What the others have said, plus the N-100 is designed for use in construction and other industries when you need to avoid breathing in things like asbestos, lead, etc. They were never designed for healthcare.
The "everything else" you refer to are good at protecting others from your exhalations, and do a decent job with protecting you too, although no mask works as well as the N-95 for pandemic protection.
